This invention relates to weighing machines and more particularly to aweighing machine especially adapted for use in laundries.

5 In commercial laundry work, it has been the practice to place adefinite quantity of goods by weight into a net bag and then washing thegoods while still in the bag. This mode of washing substantiallyeliminates the wear and tear on the goods caused by the action of therotary power driven washing machine, the net bag bearing the brunt ofthe damage heretofore inflicted upon the goods by the friction incidentto the mechanical washing processes. It is quite essential that anaccurate check on the weight of the goods be maintained, for it has beenfound by experience that when too great a quantity of goods had beenplaced in a bag, the washing process was not satisfactorily accomplishedand too small a quantity of goods is, of course, an economic loss to thelaundry. It is accordingly an object of this invention to provide aweighing device to measure the desired quantity of goods to be placed ina bag and which will hold the mouth of the bag in open position toenable the operative to readily place therein the goods to be washed.

Another object of this invention is the pro vision of a laundry weighingwherein the mouth of the laundry bag is automatically closed to indicatethat a sufficient quantity of goods to be washed had been depositedthere in and to facilitate the removal of the bag from its supports.

Other features of this invention, together with certain details ofconstruction and combination of parts, will be discussed in thespecification. and pointed out in the appended claims.

In the drawings:

Fig. 1 is a perspective view of my device with a bag in open positionthereon, as indicated by the dotted lines;

Fig. 2 is a front elevational View showing the position of the parts ofthe device after the bag has received the desired quantity of goods, theclosed bag being indicated by the dotted lines; and

SeriaI No. 206,846.

Fig. 3 is a side elevational view of my device.

In the illustrative device there is shown a base generally indicated bythe reference numeral 1, which is formed of a casting, the rear portionof which has substantially the configuration of an isosceles trianglehaving sides 2 and a base formed by a cross-piece 3. The base 1 isextended forwardly from the eX-- tremities of the cross-piece 3 to forma pair of feet 4 and 5 which are adapted to give greater stability tothe device. The feet and crosspiece 3 have cast integrally therewithenlarged portions, or bosses, 6 and 7, respectively. The bosses havescrew-threaded apertures for the reception of bolts 8 which rigidly holdsubstantially triangular standards, or fulcrum stands, 9 in uprightposition on the base. A reinforcing rib 10 extends vertically of eachstandard 9 and is adapted to give greater strength thereto.

The upper extremities of the standards are bifurcated, as at 11, saidbifurcations form ing seats for V-shaped bearing members 12 which areretained in position by means of lugs 13. Pivotally supported on thebearings 12 by means of knife edge pivots 1+1. is a U-shaped lever 15,the pivots being set into the lever during the casting thereof. Thedisplacement of the pivots is prevented by pins 16 placed across theextremities of the bifurcated standards.

To one extremity of the U-shaped lever 15 is rigidly attached an uprightarm 17 having at its upper extremity a cross-piece 18 integrally casttherewith and at a slight angle thereto, the purpose of which willhereinafter he explained. On the other extremity of lever 15 are formedthe projections 19, in which projections is pivoted the arm 20 havingacross-piece 21 similar in construction to cross-piece 18. On the lowerend of arm 20 is cast a boss which is grooved and forms with coverplate24, fastened to the boss by means of screws 23, a slot which is adaptedto act as a guide and holder for a dog 25 slidably held therein.

Rigidly fastened to lever 15 is an arcuate locking ratchet 26 whichpasses through an aperture 27 in the dog 25. A rod 28, the upper portionof which is bent to form an arcuate trip-arm 29, is held in an enlargedportion, or boss, 30 in foot 5 of base 1. The dog 25 cooperates with thetrip arm 29 to unlock the arm 20.

' Substantially centrally of the U-shaped lever 15 and extendingrearwardly is rigidly attached a beam 31 upon which is adapted to slidea balance weight, or poise 32. The poise carries a pointer 33 whichcooperates with a beam face index 34 to indicate the net weight of thegoods to be placed in the laundr bag. The poise may be retained inadjuste position by means of a set screw 35.

The sides 22 of the base meet in an enlarged portion, or boss, 36 towhich is rigidly attached a trig stand 37 into which is set a trig loop38. A shield 39 which is adapted to steady the laundry bag as it isbeing filled is suitably attached to the U-shaped lever, as by means ofscrews 40.

In operation, a net bag is suspended from arms 17 and 20 and is held inposition by being draped over cross-pieces 18 and 21. The operative thenfills the bag with the goods to be laundered, the quantity of goods tobe put in being determined by the position of the poise. The weight ofgoods put into the bag is normally between six and twelve poundsdepending upon the practice in the particular laundry. When a suflicientamount of goods had been deposited in the bag, the U- shaped lever is,by the weight of the bag and goods, tipped downwardly, the dog 25striking the trip arm 29 which releases said dog from the lockingratchet 26 and allows the arm 20 to be drawn inwardly by the weight ofthe bag. This indicates to the operative that the bag contains asufficient quantit of goods and also allows an easy removal 0 the bagfrom the cross-pieces 18 and 21.

The cross-pieces 18 and 21 of arms 17 and 20, respectively, are set atan angle in order that, when the lever 15 is tipped by the weight of thebag and contents, the device may be quickly overbalanced and the arm 20released and drawn inwardly with despatch.

Upon the bag and contents being removed the parts are quickly restoredto their normal position through the action of the poise 32.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:
